Abstract
A chair, in particular an office chair, comprises a pedestal; a seat support propped thereon; a seat supporting itself on the seat support; a backrest support mounted on the seat support; a headrest support mounted on the backrest support; and a headrest mounted on the headrest support and having a height setting mechanism for height adjustment of the headrest and an inclination setting mechanism for adjustment of an angle of inclination a of the headrest.
Description
Technical field
The present invention relates to a chair, particularly relate to an office chair.
Background technology
There is the chair of head rest very general.Head rest generally has such shortcoming, the promptly complicated arrangement for adjusting height with retaining mechanism.The adjusting of gradient is generally impossible.
Summary of the invention
Purpose of the present invention is for realizing that one has the chair of head rest, and its height and inclination angle can both as far as possible easily be regulated.Main points of the present invention are that head rest has the height arrangement for adjusting height simultaneously and is used for the device that gradient is regulated.
Comprise a base according to chair of the present invention, one is supported on chair base supporting on this base, one himself is bearing in the seat support on the chair base supporting, one is used for the back support of backrest, back support is contained on the chair base supporting, one is contained in the head rest supporting on the back support, and a head rest, and it is contained in the height adjustment mechanism that the head rest supporting is gone up and had a height that is used for head rest to regulate; With a tilt adjustment mechanism of adjusting that is used for the angle of inclination a of head rest.
Described height adjustment mechanism comprises at least one guide rail, perhaps preferably includes two guide rails.And at least one guide rail is with respect to the vertical plane bending.
According to another aspect of the present invention, at least one friction guide pad is directed at least one guide rail movably.
In addition, tilt adjustment mechanism comprises one, and this axle is supported with respect to the head rest supporting.Preferably, but axle with respect at least one friction guide pad frictional rotation fix.
Best, two guide rails pair and the common frameworks that form of two crossbeams.This framework comprises facing, is used to form the outline of head rest.In addition, facing has a cover plate.
The simple declaration of accompanying drawing
To understand other characteristics and the details of invention the explanation of the exemplary embodiment of doing from appended connection with figures, wherein:
Fig. 1 is the figure of the office chair of taking the lead to lean on;
Fig. 2 is the details of magnification ratio of the head rest of Fig. 1;
Fig. 3 is the frame construction drawing of the head rest of Fig. 2;
Fig. 4 is the cutaway view along the IV-IV line of Fig. 2; And
Fig. 5 is the cutaway view along the V-V line of Fig. 2.
The explanation of preferred embodiment
The chair of seeing in Fig. 11 particularly office chair comprises a base 2, and it supports himself on the ground with Caster 3.Being contained on the base 2 is a Height Adjustable chair post 4, detachably fixes a chair base supporting 5 in the upper end of chair post, and the seat support 6 that mat is housed is installed on chair base supporting.Being contained on the rear end of chair base supporting 5 is substantially up a back support 7, is fixed with the backrest 8 that mat is housed thereon.Being contained on the upper end of back support 7 is head rest supporting 9, is fixed with head rest 10. thereon
Be the detailed description of contact Fig. 2 to 5 of the structure of head rest 10 below.Back support 7 comprises two basic vertical and parallel bars 11, and they extend to the upper end of backrest 8 always, penetrate in the head rest frame support bracket 12 with its upper end.Carriage 12 penetrates in the supporting 13 of trunnion axis interference fit the cross section tapered reduction of this supporting with its upper end again.The free end 14 of supporting towards each other.Head rest 10 is supported also in conjunction with thereon with respect to carriage 12.
Near hole 23, interior positive 27 of piece 22 has the taper enlarging 28 in a hole 23.Therefore, between the pair 26 of axle 19 and two pieces 22, formation one wherein is placed with the doughnut of rubber ring 29.Be screwed in a time-out at two pieces, 22 usefulness screws, the conical surface near the chamber the enlarging 28 helps rubber ring 29 is pressed against on the axle 19, thereby the predetermined frictional force between axle 19 and framework 15 is adjustable.Since axle 19 be fixed into respect to supporting 13 non-rotary, therefore, the effect that head rest 10 can only resistance and putting around axle 19 pivots.Do the time spent from the outside without any power, head rest 10 can rest on any default position by any inclination angle a with respect to vertical line.At this on the one hand, axle 19 and piece 22 combinations constitute a tilt adjustment mechanism that is used to regulate the inclination angle a of head rest 10.
The polylith facing of framework 15 bags for example to make of wood.Two half-cylindrical sections 30 are contained in the bottom side of the upside and the sill 17 of entablature 17.The cover plate 31 of one bending is fixed on front and back.Cover plate 31 has that piece 22 is along the rectangle dimple 32 of its walking when highly regulating, and the part of piece stretches in this dimple 32.This makes head rest 10 that the compact as far as possible structure that is used to implement be arranged, because the gross thickness k of the facing of head rest 10 only slightly surpasses the thickness S of piece 22.The end plate 33 of the bending of two elongated holes 34 with two bendings is contained in the end face of framework 15, and axle 19 moves in elongated hole 34.Only decorate with leather or fabric as shown in Figure 1-for example among Fig. 2 with the head rest 10-shown in its facing.
Be the detailed description of the operator scheme of head rest below.In order to change the height of head rest 10, the user of chair 1 upward or following pressurization.If its power is enough to overcome given frictional force, guide rail 16 just moves in the groove 24 of piece, and its result has just changed the height of head rest 10.Because the frictional force of effect between guide rail 16 and piece 22, head rest 10 is stable on the new position of regulating, and can be once more toward gliding.If regulate the inclination angle a of head rest, the user just leans on around axle 19 pivot yaws.Because axle journal 20 is non-rotatably to be fixed in the supporting 13, so piece 22 is put with respect to axle 19 pivots.Because the frictional force between the wall in hole 23 and the axle 19, and because the frictional force between piece 22 and axle 19 of using rubber ring 29 to regulate, so only need minimum rotating torque that head rest 10 is put around axle 19 pivots.When surpassing this frictional force, just produce the pivot pendulum of head rest 10.If there is not external torque to act on the head rest 10, it is static that head rest just keeps on the position that regulates.
Because towards the back bending, so the people's of head rest 10 some leans back of adaptation the head and the profile of back.Special advantage is that when some people's leans back, the inclination angle a of head rest 10 can regulate automatically.The controllability assurance user's of head rest height top is almost leaned on axle 19 and is flushed, and the swing property of head rest 10 is then basic corresponding with people's neck.The result is to feel light and convenient when head rest 10 uses.Be also advantageous in that especially the height of head rest 10 and inclination angle can be regulated simultaneously and can infinitely be changed.In addition, the head rest 10 that can surpass 360 ° of rotations provides such possibility, and promptly the user can use it as projection or recessed head rest surface.In the position of the head rest shown in Fig. 1 and 2 10, direction is from the beginning looked, and the head rest surface is recessed into.Around axle 19 Rotate 180s ° the time, just can use opposite head rest surface.
